IMPROVEMENT IN MACHINESFOR STITCHING BOOKS WITH STAPLES..

Specification forming part of Letters Patent No. 187,189, dated February 6, 1877; application iiled December 4, 1876.

To all whom 'it may concern:

Be it known that I, JAMES C. SMYTH, of Lynn, in the State of Massachusetts, have invented an Improvement in Machines for Stitching Books with Staples, of which the following is a specication:

In Letters Patent No. 11,18() granted J anuary 5, 1864, to D. M. Smyth, a machine is described for sticking staples into blinds.

The present invention is an improvement upon the same, and relates to a means whereby the sticking mechanism is adapted to forcing the staple into and through a pamphlet or book,and clinching the same to hold the leaves together. A

In the drawing, Figure l is a vertical section of the staple-machine. Fig. 2 is a plan of the same, and Fig. 3 is an elevation partially in section.

The staplesare supplied by a shaking hopper, or otherwise, upon the inclined plate a, and slide down the same against the inclined fence b, and along the same toward the staplebar c; There is an opening at c in the plate c, leaving a narrow strip, af, of the plate a, which is of suc-h a width relatively to the staple that, if a staple presents itself in the ,position of the staple l, it slides along this strip a and falls over the bar c, and hangs thereon with the points downward; but if a staple slides along down the gutter with the points against b, as at 2, the bar portion ofV the staple overbalances the same, causing the staple to fall over the edge of cf, through the opening c', into a receptacle; and it' a staple approaches and passes upon the strip a', in the position shown at 3 or 4, the points are not supported, and it falls through the opening c.l By this construction, only those staples that are in a proper position to fall upon the inclined bar c are used, and the others are to be returned and scattered upon the plate a, by hand or otherwise.

The operator preferably supplies the staples by hand, from time to time, upon the plate a, so that there will be a sufficient number upon the staple-bar c for use in the machine.

The staple-bar cis supported in an inclined position by the standard d and head-block d,

and in this head-block d is a channel of *a corresponding sectional size to the staple, so thatl the staple can be moved vertically therein; and in this channel there is a plunger, i, connected by the link l1, to the lever h1, so that it can be moved up and down, and upon each downward movement said plunger i presses upon the staple that is at the lowest end of the staple-bar c, and presses back the spring k and carries the staple down the channel in the head-block, and drives it through the pamphlet or book that is presented at the bottom of the headblock, as hereafter described.

It is to be understood that, as the plunger 'i is drawn up above the staple-bar c,.the spring 7c returns to its position against the end of the staple-bar and supports the lowest of the staples, as seen in Fig. l4, so that the staples cannot run oiL the end of the incline, but are retained, so that only one at a time is taken away by the plunger.

The lever h1 is operated in any suitable manner. I prefer a treadle and rod.

The die m, that supports the book or pamphlet through which the staple is driven, is made with a recessed face, as seen in Fig. 3, so that thevends of the staple are bent by sliding down the inclined surface.

It is important that the book or pamphlet be pressed firmly against the under edge ot' the head-block, so that the staples will be guided in their channel while being driven. I therefore place the die m upon an arm that is pivoted at 6 and guided between the bedblocks r,- and beneath this die m there is a wedge-plate, s, that is moved endwise by an arm, h2, from the lever hl that is linked to said plate s, so that the latter slides endwise as the lever h1 is raisedand depressed.

As the lever h1 is moved to operate the plunger i and drive the staple, the wedgeplate s is moved endwise to raise the die m and press the book or pamphlet firmly up against the lower edge of the head-block d, and hold the same while the plunger drives the staple, and the ends thereof are turned up against said die m and in order to adapt the machine to dierent thickness of the books or Wfenoe b, opening o', and strip a', in combination with the staple-bar c, substantially as and for the purposes set forth.

2. The combination of the sliding Wedgeplate s and screw t, With the diem and stapledriving mechanism7 substantially as set forth.
